El chupacabra is said to suck the blood of livestock and has
been blamed
for attacks in Mexico and elsewhere.
Supposed chupacabra sightings
have always panned out to be dogs, coyotes, raccoons and other
mammals.

Likewise, there is probably nothing bizarre about the mysterious
Kentucky attacks.

While many predators from coyotes to bobcats have been known to
attack farm animals, domestic dogs in particular are known to
attack but not eat livestock. In many cases, animal dog attack
victims are left with torn and mangled ears, according to the
nonprofit Internet Center for Wildlife Damage Management.

It's not yet known whether local dogs will turn out to be
responsible for the Kentucky attacks, but dogs are certainly more
likely than a mythical creature.
